N2(g) + 5/2 O2(g) -> N2O5(g) ∆𝐻° = ?

Given:

H2(g) + 1/2 O2(g) -> H2O(l) ∆𝐻° = −289 𝑘𝐽

N2O5(g) + H2O(l) -> 2 HNO3(l) ∆𝐻° = −77 𝑘𝐽

1/2 N2(g) + 3/2 O2(g) + 1/2 H2(g) -> HNO3(l) ∆𝐻°=−174𝑘𝐽

I don't know how to get the O2(g). I multiplied the 3rd reaction by 2 and reversed the 2nd reaction to cancel 2HNO3(l), H2O(l), and H2(g). O2(g) adds up to 7/2 instead of 5/2. How to fix?

I have fairly thick, long eyelashes (about 1 cm) but they kinda point downward. However, when I curl them, it looks really nice (it sometimes even touches my eyelids when I look up) and noticeable. But it’s not as noticeable in pictures/selfies. I see girls online where you can clearly see their lashes and some of these girls’ lashes are natural with mascara of course. I was wondering if my method for putting mascara or curling is wrong. I feel the prettiest with curled lashes and I just wish you could actually see them in pictures.

My high school’s yearbook had a feature where if you scanned a picture with an app, the picture will move or feature a video. What is this called and how do I something similar to my pictures? Preferably without having to download an app or make others get the app just to see the picture move

I think there's an app for it where you scan the picture and it moves.

I don t have a license or permit, but I m turning 18 soon. Can my friend who still will still have her provisional license by the time I m 18 legally drive me?

I'm a high school student and I've had this weird feeling on the left side of my chest for almost a year. Whenever it emerges, I always feel like scratching it. The feeling doesn't hurt, it just feels like someone's lightly poking me in that area. I've never had it deeply checked and my doctor never said I had any problem with anything.

I'm trying to find the name of this anime I forgot but the main lead was presumably a guy the whole time. There's one girl with dark skin and green hair, another girl that's cute and has pink hair, and a small girl with brown hair and glasses who's actually a robot. The main lead is like a ghost/spirit at one point. I just remember the main lead, the pink haired girl, and the main villain all switch bodies in their past.

I'm printing invitations for a birthday on card-stock paper. The printer printed perfectly when I tested it on regular paper but when I printed it on the card stock paper it would always print randomly off the paper. (It only printed right once out of several prints) I tried both vertical and horizontal so I don't know what's the problem.

I took some videos on my Nikon camera and uploaded them to my iMac from my SD card. The video isn t as clear/HD as i wanted them to be and I thought it was just a problem with my camera, but my photos turn out to be very clear so I don t know the problem going on with my videos. Please help!

I want an hourglass figure but my chest size is only 30 inches. My hip size is 34 inches while my waist size is 24 inches.

So I'm in the yearbook committee and our theme this year is the galaxy , so we basically cooperate everything from backgrounds to titles with the galaxy . the prob is that i can't think of a galaxy cooperated title for one of my pages; Pet Peeves . so what would be a good, catchy ( lol it doesn't really have to be catchy ) title for pet peeves that is has something related to the galaxy, stars, etc. PLS HELP ME !!!!

another reason other than the British wanting to stop privateering.

im more into watching the romantic comedy animes but you could recommend an anime that you think really affected you or really liked

PLS DONT recomend animes w/ graphic blood , killing , nudity , and etc .
